Hogs are not exactly discriminating in what they'll eat. They'll eat stinky corn, sweet candy corn, corn with diesel (this is done to repel raccoons and deer). Once you get them used to feeding in an area, just switch to plain corn. You don't need anything complicated.
Baiting a hole with corn and kool-aid or jello powder works great especially if you add some peanut butter to the mix! Also, look inot building a pig pipe-there's lots of instructions on the internet. Works great and is portable.
Other bait stuff to use in addition to corn:
-spoiled fruits from grocery store (you may need to get permission to raid their dumpsters)
-old bread, pastries & doughnuts
-dry cat/dog food
-AND if you by chance have acces to dregs & culls from a nut processing facility....GET IT.
